Connection form of led electronic display

It is not easy to assemble the whole led electronic display, just like configuring an assembled computer, even the led electronic display is more complicated to assemble, and there are more steps to pay attention to. It is connected by many modules, and the modules are assembled by many lamp beads. The steps in this are one ring after another, and the ring must be careful, otherwise the effect of the led electronic display will be affected. . The most important thing about the LED display is in terms of connection. Once the connection is not good in one place, the next link will not work properly. So today, let’s discuss what are the ways to connect the led display? Only by understanding these aspects, the LED display will be safer and more effective, because it is also related to the high brightness power of the LED display. The power of a single high-brightness led display is very small. Therefore, it is necessary to arrange and combine multiple LED displays according to the requirements. On the one hand, it can meet the requirements of applications such as a large range, high brightness, dynamic display, and color change, and on the other hand, it can meet the driving of the driver matching the LED. match requirements. The following mainly introduces four types of LED electronic display connection forms:

1. Overall series connection form: LED1-n in the general simple series connection method are connected end to end, and the current flowing through the LED display screen is equal when it is working. The other is the improved way of series connection with bypass as 1.1.

Second, the overall parallel form: one is a simple parallel form, and the other is an independent matching parallel form. The LED1-n in the simple parallel mode are connected in parallel end to end, and the voltages on each LED are equal during operation. This kind of reliability is not high, but it also adopts the parallel form of independent matching to solve this problem, which has the characteristics of good driving effect, complete protection of a single LED display, no impact on other work in case of failure, and large differences in matching.

3. Mixed connection form: the advantages of parallel connection and series connection mentioned in the appeal are comprehensive. It also includes 2 kinds. One is the hybrid mode of first serial and then parallel, and the other is the hybrid mode of first parallel and then serial.

Fourth, the cross array form: The cross array form is mainly proposed to improve the reliability of the LED display and reduce the failure rate.
